Physics Analysis in ATLAS

The group has contributed to the physics program of the ATLAS experiment since before the start of LHC collisions. In particular, their most relevant contributions have been in the area of Higgs boson physics. The group has contributed directly, actively and visibly to the measurements of H→WW and H→ττ that led to the observation of the Higgs boson in 2012 by the ATLAS and CMS experiments and which led to the immediate award of the Nobel Prize in Physics to P. Higgs and F. Englert and the Prince of Asturias Award to CERN, P. Higgs and F. Englert in 2013. In addition to the European Physics Society Prize to the ATLAS and CMS experiments. In recent years, the group has continued to play a leading role in the measurement of the Higgs boson and related discoveries, such as the observation of the Yukawa interaction of the Higgs boson in 2015 and the interaction between the top quark and the Higgs boson in 2018, both of which are key to explaining the mechanism of mass generation of fundamental particles. In addition, the group has played a leading role in the measurement of Higgs boson pair production, results that can confirm that the Higgs boson interacts with itself (“self-coupling”) and lead to the discovery of new particles that decay to Higgs bosons. The group also contributes to the search for new physics related to the Higgs sector and Supersymmetry theories.
